Differences Between C200H-AD003 and C200H-AD001/AD002
Functions
Conversion Permission Setting
With the C200H-AD003, in contrast to the C200H-AD001/002, use designation inputs must be set in advance to
“1: Use.”
A/D Conversion Data Identification Setting
Only the C200H-AD002 has this function; the C200H-AD003 does not. Data is always output in 16-bit binary, and a
BCD display can be created using a ladder program. (Refer to page 118, Sample Program 6: Binary-to-BCD Con-
version.)
Square Root Calculation Function
The C200H-AD003 does not have this function, but an equivalent can be created using a ladder program. (Refer to
page 119, Sample Program 7: Square Root Calculation.)
Scaling Function
The C200H-AD003 does not have this function, but an equivalent can be created using a ladder program. (Refer to
page 116, Sample Program 5: Scaling Function.)
Mean Value Processing Function
With C200H-AD001/002 mean values, digital output values were not refreshed until the data was obtained from
the set number of samplings. With the C200H-AD003, however, the digital output values are refreshed with each
conversion cycle. (For details regarding C200H-AD003 mean value processing, refer to 2-5-3 Mean Value Pro-
cessing.) A function equivalent to the mean value processing of the C200H-AD001/002 can be created using a
ladder program. (Refer to page 120, Sample Program 8: Mean Value Processing.)
Upper- and Lower-limit Alarm Function
Only the C200H-AD002 has this function; the C200H-AD003 does not. An equivalent can be created using a lad-
der program. (Refer to page 114, Sample Program 3: Upper- and Lower-limit Alarm (Regular Monitoring) and
Sample Program 4: Upper- and Lower-limit Alarm (With Sequence).)
Offset and Gain Adjustment Functions
These functions have been provided for the C200H-AD003. (Refer to 2-6 Offset and Gain Adjustment.)
Input Range
The voltage and current can be converted for up to ±5% of the full input range.
Analog Input Values
The following table shows the analog input values. Digital conversion values are shown as 16-bit binary data.
Input signal range AD003 AD002 AD001
–10.0 to 10.0 V F830 to 07D0
(–11.0 to 11.0 V: F768 to 0898)
87D0 to 07D0 ---
0 to 10 V 0000 to 0FA0
(–0.5 to 10.5 V: FF38 to 1068)
0000 to 0FA0 0000 to 0FA0
1 to 5 V / 4 to 20 mA 0000 to 0FA0
(0.8 to 5.2 V / 3.2 to 20.8 mA: FF38 to 1068)
0000 to 0FA0 0000 to 0FA0
Note The figures shown in parentheses are full-scale ±5%.
